FRN-R-150 - 150Amp Fuse

FRN-R-150 - 150Amp Fuse

The FRN-R-150 is a 150-amp Class RK5 dual-element fuse built around a very specific combination of electrical and physical characteristics: 250V AC / 125V DC ratings, blade-end connections, and a compact 2.1-inch body. It's also a non-indicating fuse, so that's another detail worth checking when matching an existing installation. The bottom line: if your equipment calls for the FRN-R-150, you have several concrete specifications—not just the 150A rating—to verify before installation.

Key Features and Benefits

• 150A Class RK5 configuration – Combines a 150-amp rating with the Class RK5 form and electrical characteristics specified for this fuse.
• Dual-element construction – Matches equipment requirements that specifically call for a dual-element fuse with the FRN-R-150's published response characteristics.
• 250V AC rating – Suitable for compatible AC circuits operating within the fuse's specified ratings.
• 125V DC rating – Also carries a published DC rating for qualifying applications up to 125V DC.
• 10-second response at 500% – Useful manufacturer-specified response data for comparing the fuse with equipment protection requirements.
• Non-indicating configuration – Makes it easy to distinguish this version when the equipment specification calls for a non-indicating fuse.

Material Compliance and Certifications

The supplied manufacturer specifications identify the FRN-R-150 as CE Marked. That gives buyers a catalog-specific compliance detail to work from rather than assuming that every fuse in the broader FRN-R family has identical documentation.

No additional certifications or material-compliance declarations were included in the supplied specifications. When a particular certification or environmental standard is required for a project, verify it for the exact FRN-R-150 before installation.

Where It Works Best

• Existing FRN-R-150 installations – Well suited to maintenance or replacement work where this exact catalog number is specified and the application requirements remain unchanged.
• 150A Class RK5 fuse requirements – Appropriate for equipment specifically calling for a 150A Class RK5 fuse with matching electrical and physical characteristics.
• 125V DC applications – Can also be used in compatible systems within its 125V DC rating and 20 kAIC interrupting rating.
• Dual-element fuse requirements – A match for equipment requiring dual-element construction together with the stated response characteristics.
• Blade-style fuse connections – Intended for compatible installations requiring blade ends on both sides.
